Bearing such separation is right and wrong-bearing, need to pay attention to regular maintenance, high-speed operation, widely used in radial bearings. Single-row bearings inside and outside the ring have a deep Raceway. This commitment radial bearings used to load and the two parts of the axial load. Bearing this in the radial clearance to reduce the circumstances under greater axial loading. It replaces the high-speed angular contact ball bearings. There are many such bearing structure, including open, or closed-shielding, we can produce.
